标题[问题] 关於表格删除问题
时间Fri Sep 21 01:12:07 2012
第一次发文如有不妥麻烦告知感恩
目前正在做关於录影存档的程式 碰上於删除表格後所发生crash的问题
- (void)tableView:(UITableView *)tableView commitEditingStyle:
(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *path = [dirs objectAtIndex:0];
NSString *FileName =[[[NSString alloc]initWithString:path]
stringByAppendingPathComponent:@"/"];
NSInteger sumnumber=0,partnumber=0;
//底下的video是一维阵列存放影片 我在读video内容时将section内的row数加总
for (int j=0; j<indexPath.section; j++) {
//recordrownumber记录各section的row数
partnumber=[[recordrownumber objectAtIndex:j] integerValue];
sumnumber=sumnumber+partnumber;
}
partnumber=[indexPath row];
sumnumber+=partnumber;
//移除video内存放影片的路径
NSString *firstFileName = [video objectAtIndex:sumnumber];
FileName=[FileName stringByAppendingPathComponent:firstFileName];
[[NSFileManager defaultManager]removeItemAtPath:FileName error:nil];
[video removeObjectAtIndex:sumnumber];
[self.tableView deleteRowsAtIndexPaths:
[NSArray arrayWithObject:indexPath]
withRowAnimation:UITableViewRowAnimationLeft];
}
错误的是这一行(当我把这行注解掉就不会crash)
[self.tableView deleteRowsAtIndexPaths:
[NSArray arrayWithObject:indexPath]
withRowAnimation:UITableViewRowAnimationLeft];
其错误原因
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException',
reason: 'Invalid update: invalid number of rows in section 3. The number of
rows contained in an existing section after the update (6) must be equal to
the number of rows contained in that section before the update (6), plus or
minus the number of rows inserted or deleted from that section (0 inserted,
1 deleted) and plus or minus the number of rows moved into or out of that
section (0 moved in, 0 moved out).'

网路上找了很多资料 现在一个头两个大完全不知道该怎麽修改才是
